It's had its own movie and scores of online tribute videos, but there's nothing quite like seeing intricate Lego creations up close.

You can take the word of thousands of Canberrans on that, as kids and parents queued inside and outside Woden's Hellenic Club on Saturday to see the fruits of enthusiasts' creativity.
It was shuffle-room only as the crowds paused to capture the Brick Expo's grand stadium and war scenes, the Statue of Liberty, and the block-based movement of the slot cars and eternally popular trains.
Ria Hledik said it was her family's first visit to the Canberra exhibition, and queues of longer than 100 metres were well worth the wait for her two daughters and husband, Stephen, who surprised them with tickets on Saturday morning .
"It's phenomenal, the dedication [of the builders]," Mrs Hledik said.
"It doesn't matter if you're young or old, boy or girl; there's so many other toys focused on one gender."
Matthew O'Connell was seen in the "trains room", his nearly three-year-old son, Benjamin, enthralled as about half a dozen colourful machines moved around some of about eight rail tracks.
"He loves trains and cars – and Lego trains are the best of both worlds," Mr O'Connell said.
"I like seeing all the Star Wars creations, and seeing his reactions is definitely worth it as well."
Expo spokesman David Graham said final ticket sales were 13,380 for the weekend, making the crowd the biggest in the event's five-year history.
He paid credit to the accessible but creative plastic blocks, now in their eighth decade.
"I think [the attraction] is the simplicity and the flexibility: it's so simple a two-year-old could build it, but you can build a work of art from it."
Some impressive "paintings" made purely from Lego proved his point.
Hellenic Club president John Kalokerinos said he was proud the club could host the event, which is set to raise more than $50,000 for paediatrics at Canberra Hospital.
"When I go upstairs, everyone I see is smiling, young and old, and you can't help but smile too," Mr Kalokerinos said.
